Let the spring be stretched through a small distance d x dx dx. Then work done in stretching the spring through a distance d x dx dx is d W = F d x , dW=Fdx, dW=Fdx, where F is the force applied to stretch the spring.
What happens when you push and compress the spring and then release it?
A ideal spring has an equilibrium length. If a spring is compressed, then a force with magnitude proportional to the decrease in length from the equilibrium length is pushing each end away from the other .
How do you find the kinetic energy of a spring?
Identify the spring’s maximum kinetic energy, at the equilibrium point, as equal to the initial potential energy. Calculate the kinetic energy at any other point of displacement, X, by subtracting the potential energy at that point from the initial potential energy: KE = (0.5)kx^2 – (0.5)kX^2 .
Where is the maximum speed of a spring?
The block reaches maximum speed when the spring reaches its equilibrium length – that’s the point where all the energy stored in the spring is converted to kinetic energy.
How do you find the speed of a spring?
How do you pull a spring?
Can a spring do positive work?
Is the work done by spring force is always negative The answer is again no,when you stretch/compress a spring the work done by spring force is negetive but when you release the stretched/compressed spring work done by spring force is positive .
Can work done be negative?
Work is a measurement of energy, so it may seem odd to think that a work can be negative — but it can! Work is how much energy is done by a force over a distance.
What states have Hooke law?
Hooke’s law, law of elasticity discovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load .
Do rubber bands follow Hooke’s Law?
The stretching action of rubber bands follows Hooke’s Law , F=k x, for small applied forces. The limit of force for which the rubber band follows Hooke’s law depends on the physical properties of the band, such as cross-sectional area.
Is Hooke’s law valid for all materials?
Hooke’s law applies to a perfectly elastic material and does not apply beyond the elastic limit of any material .
How is energy stored in a spring?
Work is done when a spring is extended or compressed . Elastic potential energy is stored in the spring. Provided inelastic deformation has not happened, the work done is equal to the elastic potential energy stored.
What is half KX Square?
Brainly User. Answer: The work done on the system equals the area under the graph or the area of the triangle, which is half its base multiplied by its height, or W=12kx2 W = 1 2 kx 2 .
When traveling at top speed a roller coaster train with a mass of 12000 kg has a velocity?
Explanation: Given When traveling at top speed, a roller coaster train with a mass of 12,000 kg has a velocity of 30 m/s .
What is the greatest acceleration of the mass spring?
Closed 2 years ago. In simple harmonic motion (for example a spring moving horizontally), acceleration is greatest when the mass reaches either end of the spring . Using the formula F=ma=kx and then a=kxm, it makes sense that acceleration is greatest when x is max.
What is Max acceleration?
Maximum Acceleration captures how quickly a batter speeds up their swing from start until impact , and relates directly to the force and torque applied to the bat.
How strong is spring steel?
| Standard Annealed to spheroidized cementite | Material-No. AISI Tensile strength [MPa] (max.) | 1.1231 1070 580 | 1.1248 1075 610 | 1.1269 1086 620 |

What error did Rana make?
What error did Rana make? The acceleration should be increasing, not decreasing .
How is spring made?
- Spring Winding. First, the spring wire is fed into mechanical spring machinery. ...
- Heat Treating. Once a spring is formed, it typically needs to undergo a stress-relieving process, which will allow the spring to retain its memory. ...
- Grinding. ...
- Coating and Finishing.
Is force ever negative?
The answer to the question ” Can force be negative” is simply Yes . Force is a vector quantity and depends upon magnitude and direction. The negative symbol just identifies the direction. The force is the produce the mass and acceleration of an object.
Is spring force negative?
The spring force is also called the restoring force. The spring force is negative because the direction of the force exerted by spring is opposite to the direction of displacement . When the spring is pulled downwards it will exert a restoring force upwards.
Is spring work negative?
The minus sign indicates that the spring force is always opposite in direction to the displacement of its free end. So the work done by a spring force is always negative .
